GUSTAV E. ANDERSON, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THEFAIRMOUNT MACHINE COMPANY, OF PENNSYLVANIA.

CLUTCH.

SPECIFICATION forming part of Letters Patent No. 512,933, dated January16, 189 4.

Application filed May 31, 1893.

To all whom, it may concern:

Be it known that I, GUSTAV E. ANDERSON, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Improvement in Clutches, whichimprovement is fully set forth in the following specification andaccompanying drawings.

My invention consists of a clutch in which there is a double clutchingaction of one member on the other, the construction of parts beinghereinafter set forth.

Figure 1 represents a diametrical section of a clutch embodying myinvention. Fig. 2 represents a side elevation of one of the membersthereof, certain portions being removed.

Similar letters of reference indicate corresponding parts in both thefigures.

Referring to the drawings: A and B designate two clutch members, and Gand D designate the shafts on which they are mounted.

E designates the rim of the member B, and F the supporting arms thereof,said arms radiating from the hub G. In the inner and outer peripheriesof the rim are circular grooves or recesses H and J, in which arewedging blocks K and L, which are primarily free therein, and areconnected respectively with radially sliding heads M and N, it beingnoticed that said blocks K andL point toward each other, and said headsare on the inner side of the member A, and guided in slots therein, andretained in position by means of plates or washers P, and nuts and boltsQ.

R designates compound levers which are mounted on the member A, near thehub thereof. One end of each of said levers R is pivotally connectedwith one of the slides N, and the other end has pivotally connected withit the link S, whose outer end is pivotally connected with one of theslides M.

T designates a sleeve on the shaft 0, the same having pivotallyconnected with it the toggle levers U, the inner limb of each of whichis mounted on the hub of the member A, and having on its inner end anextension V, which carries an adjusting bolt W, whose point is adaptedto engage with the adjacent end of the compound lever B.

The operation is as follows: When the sleeve Serial No. 476.08 7. (Nomodel.)

is moved, say to the left,the toggle levers are I so operated that thebolts W are advanced against the compound levers E. This draws in thelinks S, thus pressing the blocks K into the recess H, and at the sametime forces up the blocks L into the recess J, thus causing said blocksto tighten against the walls of said recesses, and consequently againstthe rim E, thus clutching the two members A and B. When the sleeve ismoved to the right, or from the left to the position shown in thedrawings, the compound levers are relieved of their wedging action'onthe rim E, and thus the two members are disconnected or unclut'ched. Theentire movement of the sleeve T in either direction is small, themovement to lock the clutch being only from the position shown in Fig. 1to the left, until the links connecting it with the levers U are inperpendicular position, and the movement to unlock the clutch beingsimply the reverse. In said figure the distance between the wedgingblocks and the walls of the grooves in the rim are some hat exaggerated,so as to show them apart, while in actual practice the distances apartof said blocksand rim are comparatively small and appear almost incontact.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A clutch consisting of two members, one of which has circumferentialrecesses on the outer and inner faces of its rim, the other memberhaving radially-sliding heads provided with wedging blocks which move insaid recesses, a sleeve having a toggle lever pivoted to itand to thelast described clutch member, and a lever with links connected to saidsliding heads, said parts being combined substantially as described.

2. A clutch having a member with recesses in the outer and inner facesof its rim, a member having radial slots therein, sliding heads withconnecting bolts movable in said slots, and wedging blocks connectedwith said heads, a sleeve with toggle lever secured thereto and to saidsecond described member, a compound lever pivoted to said second memberand having links connecting it to said sliding heads, and an adjustingscrew in said thin in its rim, and a second member provided with aradially-sliding head with a wedging block movable in said recess,asleeve with atoggle lever pivoted thereto and to said second member, anda lever pivoted to said second member and connected by a link with saidhead, said toggle lever bearing on one end of said pivoted lever, saidparts being combined substantially as described.
